STOVE.

Specification of Letters Patent. Patented Oct. 19, 1920.

Application filed August 23, 1919. Serial No. 319,446.

To all whom it may concern: 7

Be it known that I, WALTER F. ROGERS, a citizen of the United States ofAmerica, and a resident of Chicago, county of Cook, and State ofIllinois, have invented certain new and useful Improvements in Stoves,of which the following is a specification.

This invention relates to that class of stoves in which the oven isheated by the combustion of either solid or gaseous fuel. In stoves ofthis type, a gas burner is generally mounted inside of the oven, and afire-box for the combustion ofsolid fuel communicates with a heatpassage located in the walls of and beneath the oven.

The main objects of the present invention oven adapted to serve as abaflle wall for uniformly distributing the heat from the combustion ofthe'solid fuel, and also as a conduit for delivering the secondarysupply of air to the gas burner within the oven; and to provideanwimproved form and arrangement of valve means for controlling the flowof air through said hollow partition. 1

An illustrative embodiment of this invention is shown in theaccompanying drawings, in which-- Figure 1 is a horizontal sectionalview of the oven showing a ring shaped gas burner mounted therein.

Fig. 2 is a longitudinal sectional View of the same, taken on the line2-2 of Fig. 1.

Fig. 3 is a perspective view of the improved form of hollow partition. 1

Fig. 4 is a perspective view of the improved valve means for controllingthe ad mission of air to the partition.

In the common form of kitchen range which is adapted for the combustionof solid fuel, the fire-box is generally located at one side of theoven, and the hot gases from the fire-box pass over the top of the ovendown around the opposite side thereof and then back through the'heatpassage which is located beneath the oven. In this type of stove, abafile wall or flue strip in the form of a partition is secured in theheat passage beneath the oven, so as to uniformly distribute the heatbeneath the bottom of the oven by causing the hot gases to travel in acircuitous path before they reach the smoke flue. Heretofore thispartition, which forms the baflle wall, has generally within the oven,an opening is formed in the base plate of the oven to serve as asecondary air inlet for the gas burner. In the latter construction, itis also necessary to provide a "baffie wall in the heat passage beneath.the oven to distribute the heat when the stove is burning a solid fueliIn the present invention, the baffle wall in the heat chamber and thesecondary air inlet for the gas burner are combined in a single devicein the form of a hollow partition open at the back of the stove, and theopening in the bottom of the stove is avoided. In the construction shownin the drawings, the invention is embodied in a,

kitchen range comprising" an oven 1 having a gas burner 2mountedtherein, and a firebox.3 located at oneiside of the oven for thecombustion of a solid fuel.

The top of the oven is spaced. from the top plate of'the stove, so as toform a heat passage 4 communicating at one end with the fire-box. 3 andat-the other end with a passage 5 formed at the side 6 of the stove. Thebottom of the oven is formed of double walls so as to provide a'heatpassage 7 which communicates with the fire-box through the passages 4and 5. When the stove is burning solid fuel, the heat travels throughthe passages 4, 5 and 7 in the direc'-- tion ofv the arrows shown inFig.2.

The gas burner is similar to that shown in my ,copending application,above mentioned, and comprises a ring-shaped burner seated indepressions which are formed in the inner base plate 8 of the oven, saidbase plate having an opening 9 within the area circumscribed by the ringburner. The lateral arm of the burner is also seated in a depressionformed in the inner base plate 8 and extends diagonally outward andpasses through an opening formed in the rear wall of the oven where itcommunicates with a fuel inlet and a primary air inlet.

The improved partition may be cast in one hollow piece if desired, butthe preferable construction is that shown in the drawings, in which thepartition comprises a pair of separate members 10 cast to the form shownin Fig.3 and secured together by a bolt 11. In its assembled-form, thepartition is of U-shape and comprises a cylindrical part 12 having apair of parallel legs 13 extending to one side therefrom and spacedapart as shown. The partition is mounted in the heat passage. '7' sothat the cylindrical part 12 is located in alinement with the opening 9of the base late 8. Theflegs 13 are disposed directly thezlat'eralarm ofthe gas burner, the upper edges of said legs being curved to conformto-thefdepression in the base plate 8, which forms thefiseat for thelateral arm of the burner. communicates with an" opening in the rearwall of. the oven, whichforms a secondary air inlet for the gas burner.

The valve for controlling the flow of air through the. inlet, preferablycomprises a strip of'metal 14 cast to'the form shown in Fig. 4. Thevalve 14 is slidably mounted in guideways formediin the rearwallof theoven and is adapted to be shifted into and out of position to close theair inlet.

' The means for shifting the valve '14: comprises a rod 15 rotatablymounted in bearin'gs secured'to the side 6 ofthe stove. The

rear'end of the rod 15 is-formed to provide a crank 16 which engages a'slot-17 formed at the outer endof the valve 14'so that the I rotation oftherod-will shift the valve in itsguideways. -A handle 18 is formed atthe forward endv ofthe rod 15 to facilitate the rotation thereof. In theoperation of the device, when the stove is burning asolid 'fuel,'thevalve 14 is shifted to itsclosed position-and the heat from the fire-boxpasses through the heat chamber '7 'to-arsmoke flue 19 in the usual 2way. In heat-ingJth oven bythe gas burner,

ene ath I The outer end. of the partition the valve is shifted to itsopen position so that a secondary supply'of air passes through thehollow partition to the gas burner;

"Although but one specific embodiment of this invention has been hereinshown and described, it will be understood'that numerous details-oftheconstruction shown may be altered or omitted without departing from thespirit of this invention as following claim. v g v I claim: r

In a stove adapted for burning eithe'rsolid or gaseous fuel, a fire-boxfor the combustion of solid fuel, in combination'with an oven havingaring-shaped gas burner mounted therein, a lateral arm extendingradially outward fromsaid'burner and communicat ing at its outer endwith fuel and air inlets, the bottom of said oven comprising inner andouter plates disposed in substantially oven through an opening in saidinner plate, 7

the other end communicatingwith said air inlet, whereby said'baffie wallis adapted to serve as a secondary air conduit for said defined by the Vgasburner, said baffle wall extending in the 7 same direction as saidlateral arm and hav; 7

ing its upper face shaped to conformto'the depression infwhich seated.vV r I V Signed at Chicago this 12th day of August, 1919.
